Sou​nds like it may be an issue with a 3rd party plugin you have or customization, also there might be a plugin conflict with a 3rd party plugin – you can check that by disabling then reactivating a plugin one at a time to see if you find a conflict there.
As far as I can confirm on multisite network setup plugin works just fine and as expected.
